YouTube is famous for letting users upload their short clips for the internet to see. YouTube is also infamous for hosting copyrighted material, such as music videos, cartoons, and full legnth television shows. YouTube has responded to the copyright problems by working on contracts with big producers to make the content legal. They currently make all their money off of banner ads, promotions and sponsorships. There has recently been alot of talk of the possibility of buying YouTube. Mark Cuban, a billionare, co-founder of HDNet and owner of the NBA's Dallas Mavericks, doesn't quite see YouTube as a cash cow. Cuban claims that YouTube will be "sued into oblivion" due to copyright issues, and "anyone who buys that (YouTube) is a moron" because of potential lawsuits from copyright violations. Cuban also doesn't like the advertising potential of the website. "User-generated content is not going away," he said. "But do you want your advertising dollars spent on a video of Aunt Jenny watching her niece tap dance?" Cuban also pointed out that when "Somebody puts up something really good and you get, what, 60,000 viewers?".
